<div>Hi,</div>
<div><br>
</div>
<div>I am trying to extend an event listener and the example one works fine, which just prints out every event.</div>
<div>However I want to do something more complicated than that. So I added two more dependency on top of keycloak dependencies:</div>
<div>com.codahale.metrics:metrics-core and com.readytalk:metrics3-statsd</div>
<div><br>
</div>
<div>In my IDE I was able to develop fine, then maven packages it fine. I package it by including all the dependencies (so JAR file is like 6 MB), otherwise it won’t have the dependencies (I have tried that and it complained at the runtime saying it doesn’t
have the class).</div>
<div><br>
</div>
<div>Then I start the keycloak service, it starts fine. I get an exception throw like below when I initially use the service (which is when the first event trigger happens):</div>

<div>I don’t know what could be wrong. When I googled the java.lang.NoClassDefFoundError with Keycloak I found that there was an error with Facebook integration. So I am wondering whether this is something similar and a bug with Keycloak? If not then what have
I missed?</div>
